This strategy allowed us to overcome matrix effects and to exploit second-order advantage.
The applicability to natural samples was investigated through the study of matrix effects and toxin recovery.
Accuracy, precision, cross-reactivity, matrix effects and inter-operator variability were assessed.
Chemistry and instrument design play a major role in some matrix effects and recommendations are given to minimise these or make them easier to correct.
The method was validated in terms of linearity, limits of detection (LOD) and quantification (LO Q, accuracy (trueness and precision), matrix effects, and robustness.
Combination of the QCM and microarray methods that utilize the same assay chemistry on gold are useful for overcoming clinical sample matrix effects and achieving ultra-low detection of small nucleotide biomarkers with quantitative insights.
The chemical separation scheme is designed to reduce matrix effects and consequently yield enhanced ionization efficiencies for concentration determinations of REEs without significant fractionation using solution mode-inductively coupled plasma mass spectrometry (ICP-MS) analysis.
Moreover, the proposed method was compared with direct detection or other reported methods, and the results showed that low matrix effects and good recoveries results were obtained in this work.
Under optimum operating conditions, the externally air-cooled plasma produces comparable sensitivities, M2+/M+ signal ratios, matrix effects and other analytical figures of merit as those produced by a conventional torch while using much less argon.
Several extraction solvents were evaluated with respect to the degree of soil extract-induced matrix effects and the recovery values for DPAA and PAA in the four studied soil matrices.
Measurements are taken at two different indentation depths, which represent different levels of the matrix effects and lead to the establishment of two independent equations that correlate the fiber/matrix properties with the indentation responses.
